Questions about the Waves poster

What’s on the Waves poster?

A definition and 6 facts worth remembering. A wave carries energy from place to place without permanently moving the material it travels through. Amplitude is the height — it decides loudness or brightness.; Wavelength is the distance between two peaks.; Frequency is how many waves pass per second, in hertz.; Transverse waves shake side to side — light, water.; Longitudinal waves squash and stretch — sound.; Sound needs a medium; light does not, which is why space is silent.; Higher frequency means higher pitch in sound, and bluer light in the visible spectrum.. speed = frequency × wavelength. Increase one, the other must fall.

Who is the Waves poster for?

Waves is filed under 7th Grade (ages 12–13), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.

When should you use the Waves poster?

Shake a rope and watch the wave travel while the rope stays where it is. A wall chart earns its place by being glanceable from where the work is happening, so Waves belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.

What other posters go with Waves?

Heat Transfer, Atoms and How Body Systems Work Together sit alongside Waves in the 7th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Heat TransferAtomsHow Body Systems Work Together

Is the Waves poster free to download and print?

Yes. Waves downloads as a free PDF with no account, no email and no watermark, like everything else in the 7th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Waves poster print at?

Waves is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Waves loses nothing.Printing guide
